gst-plugin-bad fails to build because changes in faad2 API are being enforced on some distros. As a result, certain functions have gone missing. Specifically:

/* MACROS FOR BACKWARDS COMPATIBILITY */
/* structs */
#define faacDecHandle                  NeAACDecHandle
#define faacDecConfiguration           NeAACDecConfiguration
#define faacDecConfigurationPtr        NeAACDecConfigurationPtr
#define faacDecFrameInfo               NeAACDecFrameInfo
/* functions */
#define faacDecGetErrorMessage         NeAACDecGetErrorMessage
 #define faacDecSetConfiguration        NeAACDecSetConfiguration
#define faacDecGetCurrentConfiguration NeAACDecGetCurrentConfiguration
#define faacDecInit                    NeAACDecInit
#define faacDecInit2                   NeAACDecInit2
#define faacDecInitDRM                 NeAACDecInitDRM
#define faacDecPostSeekReset           NeAACDecPostSeekReset
#define faacDecOpen                    NeAACDecOpen
#define faacDecClose                   NeAACDecClose
#define faacDecDecode                  NeAACDecDecode
#define AudioSpecificConfig            NeAACDecAudioSpecificConfig


For faad2-2.5-2 [faac-1.25-2] on a Fedora system, the header file faad.h contains only a warning and another include file:

   /* warn people for update */
   #pragma message("please update faad2 include filename and function names!")

   /* Backwards compatible link */
   #include "neaacdec.h"

The current FC7 version of neaacdec.h does *not* contain the macros listed above.  

Adding these definitions allows gst-plugins-bad to build.
